Inventory in Kalispell and Bozeman means your materials are on site when you need them — no waiting on distant distribution centers.
High-wind loads, heavy snow, and freeze-thaw cycles require the right products. We know what performs in the Flathead and Gallatin Valleys.
Trade accounts, volume pricing, and the responsiveness that national distributors simply can't offer.
From Kalispell we cover the Flathead Valley and northwest Montana. From Bozeman we cover the Gallatin Valley and the southwest. Two yards means faster fulfillment, deeper stock, and a team that answers the phone.
Ready to talk materials? Email whichever yard is closer and we'll get back to you within one business day. We serve roofing and siding contractors, general contractors, and builders. Contractor accounts welcome at both locations.
